    Abstract

    Underwater Sensor Networks (UWSN) utilise acoustic
    waves with comparatively lower loss and longer range in
    underwater environment than electromagnetic waves. However,
    energy remains a challenging issue in addition to long latency,
    high bit error rate, and limited bandwidth. Thus, collision
    and retransmission should be efficiently handled at MAC layer
    in order to reduce the energy cost and also to improve the
    throughput and fairness across the network. In this paper,
    we therefore propose a new reservation-based distributed MAC
    protocol, which employs a duty cycle mechanism to address the
    spatial-temporal uncertainty and the hidden node problem to
    effectively reduce collisions and retransmissions. Our extensive
    simulation study reveals that our proposed protocol can efficiently
    handle the traffic contention to achieve significant improvement
    in terms of energy consumption, throughput, and fairness.
